7.7.7 Verifying the Base or Expansion Module Controller Installation
1.
Using the OCP or RMI, click or tap
Status > Library Status > Module x
to view the controller status.
2.
Using the OCP or RMI, check for events; the event that indicated the controller was faulty should be
cleared.
3.
If replacing the Base Module controller, restore the previous settings by restoring them from a file of
saved settings, or by entering them using the OCP or RMI.
4.
If the UID LEDs are still illuminated, deactivate them using the RMI.
5.
Resume the host applications.
7.7.8 Powering on the Library
Power on the library by pressing the power button on the Base Module just below the OCP; the green
light will illuminate. When the library is powered on, it inventories the tape cartridges in the magazines,
checks the firmware version of all modules, configures the tape drives, confirms the presence of the
existing modules, and searches for any new modules.
